Umeå and China group develop ‘random’ laser made from bio-materials

Breakthrough in Laser Technology

Researchers from Umeå and China have developed a "random" laser made from bio-materials, including birch leaf and peanut kernel.

"Our study shows that it is possible to create advanced optical technology in a simple way using only local, renewable materials,"

said Jia Wang, Associate Professor at the Department of Physics, Umeå University. This innovation could lead to a cheap and accessible tool for diagnostics and imaging.

The achievement is described in a paper in Nanophotonics, showcasing the possibility of creating advanced optical technology using simple, local materials.
